Regional data files (Dati per Regione):¶
- Struttura file giornaliero: dpc-covid19-ita-regioni-yyyymmdd.csv (dpc-covid19-ita-regioni-20200224.csv)
- File complessivo: dpc-covid19-ita-regioni.csv
- File ultimi dati (latest): dpc-covid19-ita-regioni-latest.csv
Below we use the 'dpc-covid19-ita-regioni.csv' file (updated on daily basis, so far).
In addition, we get regional population size from https://it.wikipedia.org/wiki/Regione_(Italia) for per capita measures
